Nearly 20 patients, mostly elderly, and a nurse have been killed in a fire at a hospital in South Korea.
Six others are in critical condition after fire broke out at Hyosarang Hospital at Janseong county, about 300km south of Seoul.
Most of those who died are thought to have been in their 70s and 80s and died of suffocation.
The fire was put out within half an hour.
According to the BBC, police said they had detained an 81-year-old patient suffering from dementia after security video footage showed him entering an area where the fire began.
The fire broke out shortly after midnight at a three-storey annex.
Many patients on an upper floor of the building were unable to evacuate as their rooms were filled with smoke from the fire, the report added.
